Torsion And Bending Properties Of Edgeendo Files, Chad Hansen Apr 2016

Torsion And Bending Properties Of Edgeendo Files, Chad Hansen

Master's Theses (2009 -)

Introduction: One important step of root canal therapy is the process of cleaning and shaping each canal. This process involves using endodontic rotary files combined with chemical irrigants to remove pulpal remnants and infected dentin from the canal while eliminating pathogenic bacteria. It is essential to maintain proper canal anatomy while cleaning and shaping. The challenge for the practitioner is to select a rotary file system that will be flexible enough to maintain canal anatomy but strong enough to prevent breakage under normal use. File flexibility allows for better maintenance of canal anatomy. A file’s resistance to torsional fatigue reduces …

Viability Of Human Periodontal Ligament Fibroblasts After Storage In Save-A-Tooth, Emt Toothsaver And Hank's Balanced Salt Solution, Wonhee Lee

Master's Theses (2009 -)

Introduction: Viability of periodontal ligament (PDL) cells is a key prognostic factor fora replanted tooth following avulsion. Dehydration results death of PDL cells, which in turn causes ankylosis upon replantation, followed by replacement resorption. Hank’s Balanced Salt Solution (HBSS) has been recommended as the standard storage medium for an avulsed tooth. Save-A-Tooth and EMT Tooth saver (Dentosafe)are commercially available tooth storage media. With the best of our knowledge no study has yet compared these media for their effective tooth storage times. The aim of this invitro study is to evaluate Save-A-Tooth, EMT Toothsaver (Dentosafe), and HBSS for their effect on …

The Incidence Of Root Dentinal Micro-Cracks Caused By Reciprocating And Continuous Rotary Instrumentation, Stephen N. Schroeder Jan 2016

The Incidence Of Root Dentinal Micro-Cracks Caused By Reciprocating And Continuous Rotary Instrumentation, Stephen N. Schroeder

Theses and Dissertations

The aim of this study was to compare the incidence of root canal dentinal micro-cracks after canal instrumentation using reciprocating files (WaveOne Gold® and Twisted Adaptive®) and continuous rotation files (Edge Evolve® and EndoSequence®) in an ex-vivo benchtop study. This project used a novel methodology of finding dentinal defects using the “K-cube”, which allows evaluators to visualize sectioned root surfaces before instrumentation and after instrumentation. Mesial roots from 40 human mandibular first molars were divided into 4 groups of 10 for each file type. Root section pictures were taken with a Zeiss Discovery V20 stereomicroscope before and after canal instrumentation. …

Comparison Of Treatment Planning Decisions When Combining Cbct And Digital Radiography Verses Digital Radiography Alone, Mckay Barlow Packer Jan 2016

Comparison Of Treatment Planning Decisions When Combining Cbct And Digital Radiography Verses Digital Radiography Alone, Mckay Barlow Packer

Theses and Dissertations

Cone beam computed tomography (CBCT) is the recommended imaging modality of choice for evaluating previous endodontic treatment (1). The aim of this study was to compare treatment planning decisions made when evaluating previous endodontic treatment to determine if treatment planned and projected prognosis differs when digital radiography is used alone or in combination with CBCT. A retrospective chart review was conducted. Patients for whom a CBCT was taken were included in the study. Twenty-eight patients qualified. Patient’s periapical digital radiographs (Dexis©) were evaluated by 2 calibrated endodontists, a treatment plan was identified and a prognosis was projected. Later the same …
